Mercado Bitcoin freezes deposits and withdrawals after security incident

Mercado Bitcoin, one of Latin America's largest cryptocurrency exchanges, has frozen deposits and withdrawals following a security incident, the company announced. The exchange, which serves millions of Brazilian users, did not disclose the scope of the breach or whether customer funds were affected, leaving the size of potential losses unclear. The halt in withdrawals is likely to test user confidence and could draw scrutiny from Brazilian regulators, who have been increasing oversight of the country's growing crypto market. The incident underscores ongoing security challenges for centralized exchanges in the region. Investors and users should watch for updates from Mercado Bitcoin on the incident's cause, the status of customer funds, and a timeline for restoring services.
